Android Paths for real time charting

I'm trying to create a real-time charting utility in android, and for the most part it works, except that when I get too many data points in one of my Paths it breaks openGL. I'm using paths because I'm transforming the entire dataset via matrix when a passed in value is outside the current bounds of the graph. Am I going about this the wrong way? is there a better/more appropriate API for this sort of thing? I'd be happy to trim the path to the current bounds if that were possible/I knew how to do it. Thanks!

rendered into a texture

Since turning on hardware acceleration everything gets rendered as a texture and there is a size limit for textures. If you break down the larger shapes into smaller ones, that will solve your problem. Or just turn off hardware acceleration:
